Autoconf AC_CHECK_SIZEOF always 0 on CentOS

I use GNU Autoconf 2.63 on CentoOS 6.3 32-bit. In my configure script I check the sizes of some types, like:

AC_CHECK_SIZEOF(char)
AC_CHECK_SIZEOF(int)
AC_CHECK_SIZEOF(long)

, but the result is always 0 when running ./configure:

checking size of char... 0
checking size of int... 0
checking size of long... 0

The same configurations run fine on Mac OS X SL and Ubuntu though.

Any ideas why AC_CHECK_SIZEOF returns 0 on CentOS?

Seems that it was a lib that I linked in that was missing, when I added the correct symbolic link to the lib the AC_CHECK_SIZEOF returned the correct values.
